May be I misunderstand smth., but MACRO is pre-processor and takes place
before compilation starts.
mpl::size<...> is a template instantiation which takes place during
compilation and after pre-processing.
Making pre-processor understand C++ templates is probably impossible (I
think to write a compiler would be easier ;)

Is there a MACRO which returns a constant when evaluating the size of an mpl sequence.
Here is what I'm trying to do:
#define MY_MACRO (N) CREATE_FOO_BAR_FN##N
#define SUPERFUNK (CLASSA, ...)\ CLASSA { \ typedef mpl::vector<__VA_ARGS__> v0; \ MY_MACRO ( ??SOME_BOOST_MACRO??(mpl::size<v0>::value) ) \ } \
If seems like this should be possible given that I can do the following:
BOOST_MPL_ASSERT_RELATION(mpl::size<v0>::value, ==, 0);
